Anyone know if this driver will still enable audio after a VT switch? The previous version would stop working (the audio part) after switching back and forth to the console.

HDMI uses the spare bandwidth in the horizontal and vertical video sync to transmit additional data, like audio or info packets.
Getting the audio data from the application and stuffing it into packets is the job of alsa. Programming the hardware to mix those packets into the video data is the job of my patch. Alsa simply can't to this, because you need to know what's the pixel clock (the display resolution) of the current video mode.
And yes, i think kernel mode setting would be a better way doing this.

Multichannel output and AC3/DTS path through won't work at the moment do to limitations on the alsa side. The latest alsa beta 1.0.18rc2 introduce multichannel output, but i don't have the hardware to test this, if you want to volunteer just PM me.
About the content protection, in my opinion that's nothing more than marketing. The HDMI Standard states clearly that if content protection should be used is up to the source device, which in this case the x driver controls.
